i gave a friend a block that i was told to be a 400. it was only a 351. he had it machined heads rebuilt new pistons crank the whole 9 yards. now he wants me to buy it back because he bought a cummins to put trying to decide what to do. my 400 is getting weak and was really want to stick with the bigger motor.
